The Trematodes com prising the subject-matter of the present 
work were collected by officers of the Institute and forwarded 
to me from time to time by the director, Dr. Anton Breinl, 
together with notes on the location of the parasites in their 
hosts and on the methods of preservation employed. The 
specimens were fixed for the most part in hot 70 per cent, 
alcohol, or in sublimate acetic, hot or cold; and, in cases 
where the form of the worm seemed to require it, some were 
fixed under slight pressure. The specimens converted into 
whole mounts I have generally stained in Ehrlich’s or 
Delafield’s haematoxyliu and cleared in clove oil ; all the forms 
except two, which were represented by single specimens, were 
studied by means of serial sections as well as in whole mounts. 
I wish to thank Dr. Breinl for giving me the opportunity 
to study these forms, some of which presented some very 
interesting features : I have also to thank Professor Haswell, 
in whose laboratories the work was carried out, for valuable 
suggestions and criticism, as well as for the loan of much of 
the literature from his private library.
